The preferred manner of manipulating this tool is fully set forth in my above mentioned copendin application and consists in anchoring 1118 post 9 to the latch carryin end of the rim, inserting the hooks of lin s 12 into apertures 13, then swinging the lever 11 for causing the apertured and of rim 1 to move inward away from the hook 3 and over toward the anchored post the lever 11 swingin ast its fulcrum and moving the pivots 0 links 12 below the lane of the pivotal connection between the ever and it's fulcrum post. In this collapsed condition of the rim a tire may be removed and another tire applied readily and then the rim is restorcd to its normal circular condition by a reverse movement of lever 11.

he means for anchoring the fulcrum post in said co-pending application, however differs from that disclosed herein. The sai anchoring means in the present structure consists of the plate 6 coiiperating with the flange 10 and guard 14. The method of operation of the tool and the manipulation of the rim are otherwise identical with that of the said co-pending application. In the present improved structure, the tool is a plied by inserting the flange 10 through t c enlarged end portion of slot 7 the enlargement 7 {being sufiicient to accommodate the introduction of the flange 10 as clearly indicated by the dotted lines in Fig. 3. The post 9, after the flange 10 has been introduced through the enlarged end of slot 7 is moved laterally for positioning the flange 10 beneath the flange 8 and then the post 9 is slid along the slot 7 until it arrives at that terminus opposite the enlarged end. In this position a maximum amount of flange 8 is overhung by guard 14, and a maximum amount of the flange 10 is overhung by flange 8. The parts are proportioned for having the undercut space of slot 7 snugly receive the flange 10, and for having the space between. guard 14- and flange flvsnugly accommodate ilrmgfi 8, so that the flange S effectively pre vents any Wabbling of the post 9 during operation. When the post is in this position and the links 12 have been caused to engage the apertures. 13 the tool is in position. for

F manipulating the rim as above described.

After the intercl'nmgo of tires has been accomplished and the tool restored to the iniir-ei position, the links '12 are released from b,..- ngageinent with the apertured end of he rim, then the post is slid back to a position for bringing the flange 10 into register e iili the enlarged end of slot 7. 'll'ieroupon, fine post i liilml from the. slotand the rim is u-wdy for use.

l t obv ous, of course. that ll'm'irzld of 7, 8 and 9 is the utilizing a separate plate 6 the material of the rim 1 may be stamped to form the tool reciving slot rovided in plate 6, but in such event th depression in the rim would necessarily be covered by a plate at the exterior surface of the rim for protecting the inner tube of a tire carried by the rim. Suchj structure is seen in Figs. 7, 8 and 9 wherein the material of the base 1' of the rim is'slam ed andofl'set inward formin longitudinal y extending flanges 8', 8'. an transverse flanges 8", 8 the flanges 8' and 8" being blended into each other in the course of formation, being shaped to produce an undercuts 0t 7" similar in form and function to the slot 7, and having the enlargement 7" similar in form and function to the enlargement 7'. The opening through the base 1' Wl'llCll would otherwise result from the stamping of the flanges 8 away of material for producing slpt 7B is closed by a cover plate 6' whose side and end edges are formed with inwardl extending flanges 6" shaped to snugly t the curved inner faces of the flanges 8' and 8' The inner faces of the flanges 6 are prefer ably straight so that the undercut portions of the slot 7' are lar surfaces. The operation of the tool in connection with the structure seen in Figs. same as that above de scribed. It is apparent, of.course,.that the plate 6 may be fixed to the base 1' n any appropriate manner, such as by welding or riveting. r

In Fig. 10 is shown a further embodiment of the invention wherein the plate 6', corresponding in function to plate 6, is fixed to the inner face of the base 1' of the rim. The plate 6 is formed with a slot 7 which has one end open at 7 for enabling the introduction of the flange 10 f the tool with a lateral sliding movement in .ieu of the introduetion cndwise as is shown in applying the tool through the enlargementj'. In the operation of the structurqlseen in Fig 10, the manipulation of the tool is the same as that above described and its application to theplate consists merely in sliding the tool across the rim through the entering and 7" of the slot 7 and then along the slot in a direction toward the locking hook 3. In this position the tool is manipulated as above described and after the operation is completed the post 9 is slid out of the slot 7' by a reverse movement to that of its introduction. a
